Run aplay -lv . That will show you the devices that alsa thinks are on your system. Sometimes, a video card will look like a sound device to alsa. And if you have more than one sound device, they can be loaded in different order each time. There is a way to pin devices to locations in alsa. It has to do with putting a file in /etc/modprobe.d. A search should turn up the technique and some samples if you need it. You can also check whether your device is configured correctly under alsa using alsamixer -c[device number]. Make sure that everything is turned on, and the volumes are reasonable. Alsa is under pulse, so if it isn't configured correctly, pulse will have problems. -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
